Claims. (Cl. S12- 323) The present invention relates to an improvedmeans and techniques whereby a component such as, for example, a chassisfor radio equipment may be mounted in ancabinet or other similarstructure from and into which said components may be conveniently moved;and, more specically relates to an improved slide structure upon whichsuch components may be conveniently mounted in different orientedpositions for convenient accessibility.

In general, the present arrangement contemplates a slide structure whichmay be conveniently mounted on the inner spaced vertical walls of acabinet with a pair of parallel extending slide members arranged toslide horizontally into and out of such cabinet. Such slide members areof unique construction in that a component, such as for example achassis for radio equipment, may, in turn, be slidably` mounted on suchslide members and be maintained on such slide members in diiferentoriented positions to allow convenient access to the various portions ofthe circuitry included on such chassis. Although the present inventionis described specifically in relationship to a radio chassis, it isunderstood, of course, that the arrangement described and claimed hereinmay be used to support a component other than a radio chassis.

A general object, therefore, of the present invention is to provide animproved structure of the character outlined above.

Another object of the present invention is to provide an improved slidestructure of this character which is sturdy, simple, and relativelyinexpensive considering the various functions and results obtained.

A speciiic object of the present invention is to provide an arrangementof this character which serves to maintain the aforementioned componentin any one of three extended positions as illustrated in Figures 7, 8and 9, herein. l

The features of the present invention which are believed to be novel areset forth with particularity in the appended claims. This inventionitself, both as to its organization and manner of operation, togetherwith further objects and advantages thereof, may be best understood byreference to the following description taken in connection with the-accompanying drawings in which:

Figure 1 illustrates a view in side elevation of the righthand slidestructure which is adapted to be mounted on an inner vertical wall of acabinet, and without the component, i. e., radio chassis mountedthereon;

Figures 2,13 and 4 are views taken generally in the direction indicatedby the corresponding lines 2 2, 3--3 yand 4-4 in Figure l, it beingnoted that Figures 2, 3 and 4 also include a portion of theaforementioned cabinet wall;

Figure 5 is a perspective view showing a portion of the slide structureillustrated in Figure 1;

Figure 6 illustrates the slide structure in its retracted positionwithin a cabinet, and with the radio chassis mounted thereon;

Figures 7, 8 and 9 illustrate three positions in which the radio chassismay be supported on the slide structure when such chassis and slidestructurey are moved outside the confines of the cabinet;

Figure 10 is a view in side elevation, similar to the view in Figure 1,of a modiiied slide element.

Figure 11 shows a view in side elevation of a cabinet mounting threeslots embodying the features of the present invention with one of theslots moved to extended position and with the component mounted thereonin a different position than that shown in the preceding drawings.

Figure 12 illustrates another position in which the chassis may bepositioned.

For purposes of simplicity, the drawings herein illustrate the structureof only one of the pair of slide elements, the particular one which isillustrated being the right-hand slide element, and it is understoodthat the other slide element, namely, the left-hand slide element, isconsidered, in structure, to be a mirror image of the right-hand elementwhich is now described in detail.

'I'he right-hand slide element and the left-hand slide element are eachmounted on opposite inner vertical walls of the cabinet 10 to extendgenerally horizontally, such slide elements being mounted on suchvertical walls by a corresponding so-called mounting pad as illustratedin Figurev 3, with such pad 12, however, extending horizontally, asshown in Figure 1, only a fractional portion of the length of the slideelement 14 illustrated therein. Each of the mounting pads 12 is mountedon a corresponding cabinet wall by six fastening elements such as rivets15 as shown in Figure 3. Each of the mounting pads 12 has aiiixedthereto, two horizontally spaced axles 17, 18, which rotatably supportcorresponding rollers 19B and 20B.

These two rollers 19B, 20B on corresponding mounting pads 1.2 serve tosupport the corresponding right and left-hand slide elements 14 as wellas the box-shaped component 20, i. e., radio chassis mounted on suchright and left-hand slide elements.

In general, the slide element 14 comprises an elongated member having asillustrated in Figure 5, an outwardly extending upper flanged channel ortrackway 22, for the aforementioned rollers 17, 18; a lower inwardlyextending flanged channel or trackway 24 for accommodating the rollers26 and 27 of the chassis 20; a vertically extending and inwardlydisposed anged channel or trackway 46 which is in communication with thehorizontally extending trackway 24; and, in addition, there is thetrackway 47 which is in communication with the upper end of the trackway26 and which is defined by the 45 angle brace member 30 as well as therear side of a portion of the flanged channel which deiines the trackway46. The aforementioned portion of such trackway has the referencenumeral 32.

Normally, the rollers 19B and 20B are disposed in their trackway 22, butsuch slide 14 may be removed from the cabinet 10, if desired, byremoving the clevis pin 34 (Figures 1 and 3) which normally serves toclose the end of such trackway 22 yand to thereby serve as a stopmember, such clevis pin 34 being normally threaded through spacedapertures and carrying a conventional hairpin type of retaining spring36.

The component 20, which is generally box-shaped, has two spaced wallsupon each of which is rotatably supported the horizontally disposedrollers 26 and 27 which, in the retracted position of the slidestructure and chassis, are disposed in the horizontally extending lowertrackway 24. As illustrated in Figure 6 wherein the front panel 20A ofthe component 20 is substantially flush with the vertically extendingface of the cabinet 10 such front panel 20A has mounted thereon aconventional handle 40 which may be conveniently grasped for purposes ofpullingsuch component Z0 out of its retracted position illustrated inFigure 6 to a position indicated generally in'Figure 7 wherein theforward chassis roller 27 is disposed in the vertically extendingtrackway 46. It is oblwed that.the verticallytextendingtrackway -46,twhile in communication with the horizontally extending-,track-,my-24,extendsrbelow such.trackway24 so that whentthe handleofthefcomponentlifis released the componentZO -assumes the positionillustrated in Figure 7. The-.eiect oft-,thisfis that theffrontpanel20A. isinclinedwithtrespect .to .the `vertical-toliallow moreconvenientaccessto elements carried by such component.2,:also assuring apositivelock `twhich prevents roller y27 .from moving .horizontally untilchassis 20 is lifted vertically and roller 27 .is placedrintrackway 24.

Once extended, as illustratedinfFigure7, thecomponent`oriztzhassist).may, be moved manually'to either` one of the ,two,self-supporting, positions illustrated: in Figures'S` and `9, .orindeed, .suchchassis 20tmay be .conipletelyrremovcd .from'thexslideelements :by removing the removable "pin 50 which eserves `generally ast'a `stop member or closure `ferfthe upperendof the vertical channel 46.'Thepin 50 passes throughispaced aperturediportions of the'r track- `way46Uandis normally retained bythe hairpin type of retaining spring 52(FigureS).

It is noted that when the chassis V20 is manuallymoved `from its`position illustrated `in Figure -7 toits position illustrated in Figure8, the frontjpanel 20A assumes a hori- .zontalposition thereby allowingconvenient access to the normal bottom side of the chassis 20.

`When .thechassis 20 is moved from its positionillus- .trated in Figure8 to its-position illustrated in Figure19 .wherein the front roller 27is supported on the upper side of' the channel member 22, thefrontgpanelZOA is inclined Vat `an angle of approximately 45 below-thehorizontal.

It is vthus observed that .the chassis20 may be supported on fourpositions of stable equilibrium onrthe slide ,elementsfli While thechassis 2t) is manipulated to its yvariousjpositions as illustrated inrFigures 6, 7, Sand 9, 'the slide elements 14 arepreferablylocked nposition Vrelativeto `the cabinet10, and for that purposelthe str ucturenow described in connecticnfwith 'Figure 4 is provided. Theislideelement 14 is yprovided with an aper- Vtured,portion.14A adapted toreceivethel circular locking pin 60 -which is mounted on the .lower freeend of a cantilever `supported strip of lspringsteelzB. T he-upperend-of'such-strip 63 is fastenedas shown in :Figure 4-to-themountingpadflZ while the lowerend of such strip V63 has mountedthereon the L-shaped releasinghandle 64 .toallowfconvenient:automaticreleasing or retracting 'of the Vlockingpin 60from the locking aperture 114A, saidlreleasing handle being operatedbypushing thechassis120 into the-housing T10 (in a normal manner) until'chassis ,pusl1es release pin 64 out of the way b y means of acamsactionincorporated into the element 64.

;lt,is observed'that this locking arrangementjs automatic in the sensethat when andas'the slide. is pulled out of the cabinet,fi.,e., fromits'retracted position shown in Figure 6, thelocking pin 60, beingpressed by'therspring lstripft;automatically enters the lockingaperture^14A.

Once the'slide elements 14 arethus locked with respect to -the cabinet,such slide elements 114 provide stable supporting elements, and as armatter of fact, :it 4is then relatively easy tomanipulate the chassis20to a position wherein it may be supported `on 4thebfree :lends ofsuchslides with the panel.20A extending verticallyasindicated in Figure 6,but of course, with thelentire'chassisfextended from the cabinet'10.

fTheslide element14illustrated .in themOditied arrangement: as:shown:inYFigure 10 is essentially fthe'same as Athe vslide elements .heretoforedescribed with, however, 'one essentialfditerence, suchdifferenceresiding-in themanner in Whichithelpreviously mentionedltrackway-KTisde'ned 4In Figure .16,.such trackwayrorlguideway 47,zomprises generally 'a 45 angle extendingslotted portion in the 45.anglebracket 130. In Asuch caseyaslinitheprcviously Tellers.

described arrangement, the angle brackets and 47, as the case may be,each serve an additional function, namely as stop members for limitinglateral movement of the box-shaped chassis 20.

Figure 11 illustrates an additional position of stable equilibrium ofthe chassis where the roller 26 is engaged in the trackway 24and'theroller 27 is engaged in the trackway 47. Thisrplacesrthe ychassis20 in a position 45 degrees above the horizontal. This allows access tothe undersidefof'the chassis wherein said chassisisoneof a number .ofelectronic, radar or'radiochassisinstalledin a vertical rack as shown inFigure 1l.

FigurelZ shows .still another fposition 'oftstable equilibrium in whichthe chassis may be positioned. The position shown inFigure 12'isachievedby removing the clevis pin 50, removing one roller, i. e., thetop roller on each side and revolving the unit through a degree arcwithfthe roller.26 stillheldin positionlinthe traekwayf, .This allows`the t chassisr20 to `be-suspended below the level of the opening ofthecabinet 10,'allowingtfreeaccessilo the `interior of the Acabinet-without the `necessity yof 1 disconnecting-any cablesorharnessesattached betweenethe `chassis 20 andthecase 10.

It islnotedthat in each position, particularly as shown inrFigures 2,3,7-and 9, and the'verticaltposition, there is positive lockingtot' thechassis with respect torthe slides and cabinet, occasioned `by therelativepositioningot'tthe This feature is,consideredimportant, sinceper .sons working with the equipment iare lprevented rfrom .beinginjured due to'relativelmovementof the `chassis once-ittispositioned inone `of the-positions illustrated.
